Let f(x)= -4x+7 and g(x)= 10x-6. Find f(g(x)).
<em>FYI: f(g(x)) can also be written as (f</em><span><em>○g)(x).
</em>What this really means is to take x and put it through g, then through f.
Since we don't have a specific value for g, we can just put that x value through f,
<em>
</em>g(x) = 10x-6
f(x) = -4x+7
f(g(x)) = -4(g(x))+7
f(g(x)) = -4(10x-6)+7
f(g(x)) = -40x+24+7
f(g(x)) = -40x+31<em>

Answer:
Required A. radious of the cylinder is B. there is no change in radious due to change in height.
Step-by-step explanation:
Given volume of the cylinder is 728, that is we know for a cylinder with height h and radious r, volume V is,
A. To find radious of the cylinder :
which is the required radious.
B. To find change of radious due to change in height :
If the height h of the cylinder change to then radious,
From (1) we get,
Squaring both side we get,
Which shows that change of height dosen't effect on radious.
Answer:
<u>The correct answer is G. $22,436.40</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Jelena's average annual salary = $ $53,420
Expected annually pension to receive from Social Security = 42% of her average annual salary
2. How much can Jelena expect to receive from Social Security annually if she were to retire today?
Expected annually pension to receive from Social Security = 42% of her average annual salary
Expected annually pension to receive from Social Security = 53,420 * 0.42 = $ 22,436.40
<u>The correct answer is G. $22,436.40</u>
ANSWER: u=4
2( 4u -9) = 14
8u -18 = 14
Add18 from both sides.
8u -18+18= 14+18
8u= 32
Divide both sides by 8.
8u/8= 32/8
u=4
Answer:
Simplifying
8a + -6 + a + -1 = 0
Reorder the terms:
-6 + -1 + 8a + a = 0
Combine like terms: -6 + -1 = -7
-7 + 8a + a = 0
Combine like terms: 8a + a = 9a
-7 + 9a = 0
Solving
-7 + 9a = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + 9a = 0 + 7
Combine like terms: -7 + 7 = 0
0 + 9a = 0 + 7
9a = 0 + 7
Combine like terms: 0 + 7 = 7
9a = 7
Divide each side by '9'.
a = 0.7777777778
Simplifying
a = 0.7777777778
